Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary ...

A study published in the journal Cell provides the clearest evidence to date that people infected with influenza actively expel infectious virus into the air and that the amount released varies enormously between individuals.

Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist ...

A fascination with fish gills has led researchers at Cornell to develop a bio-inspired approach to mixing heat and molecules in fluids—findings that could inform future biomedical devices, heat exchangers and soft robotics.

Can using a large language model (LLM) make a person more creative? Prior work has shown that using LLMs can make creative outputs more homogeneous, but this homogenization could stem from the specific LLM used or from widespread ...

Researchers have discovered that some of the elements of AI neural networks that contribute to data-privacy vulnerabilities are also key to the performance of those models. The researchers used this new information to develop ...

AI-generated images and videos pose a threat to democratic processes and undermine trust within society. Researchers at ETH Zurich have now developed chip technology that enables verification of the authenticity of sensor ...

Methane is a powerful greenhouse gas that is second only to carbon dioxide in driving up global temperatures. But it doesn't linger in the atmosphere for long thanks to molecules called hydroxyl radicals, which are known ...

Following the beginning of the COVID-19 outbreak, lateral flow assays (LFAs)—the category of test strips in which the presence or lack of a pink line indicates whether a specific molecule, like a drug or a virus, has been ...

Almost all living things have an internal 24-hour clock that remains accurate regardless of temperature or other environmental changes. This clock is a highly sophisticated yet simple timekeeping mechanism that is critically ...

Several insect species, including ants, honeybees and termites, live in highly organized societies, also known as social insect colonies. Insects living in these colonies can take on different roles, such as reproducing, ...

Researchers from Xi'an Jiaotong-Liverpool University (XJTLU) in China have developed a streamlined process that makes it easier to produce tiny therapeutic particles released by cells, called exosomes, which are being explored ...
